You can create or edit a PowerPoint file with the Syncfusion® UWP PowerPoint library. The below are the steps.
Create a PowerPoint file in UWP
Step 1: Create a new C# UWP application project.
Step 2: Install the Syncfusion.Presentation.UWP NuGet package as reference to your .NET Standard applications from NuGet.org.
NOTE
Starting with v16.2.0.x, if you reference Syncfusion® assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion® license key in your application to use our components.
Step 3: Add a new button in the MainPage.xaml as shown below.
<Page
x:Class="CreateUWPPowerPoint.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:CreateUWPPowerPoint"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid>
<Button x:Name="button" Content="Create Document" Click="OnButtonClicked" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</Page>
Step 4: Include the following namespaces in the MainPage.xaml.cs file.
using Syncfusion.Presentation;
using Windows.Storage.Pickers;
using Windows.Storage;
Step 5: Include the below code snippet in the click event of the button in MainPage.xaml.cs, to create a PowerPoint file and save the PowerPoint document as a physical file.
Create Presentation instance:
//Create a new instance of PowerPoint Presentation file
IPresentation pptxDoc = Presentation.Create();
Add a new slide
//Add a new slide to file and apply background color
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.TitleOnly);
Apply Background
//Specify the fill type and fill color for the slide background
slide.Background.Fill.FillType = FillType.Solid;
slide.Background.Fill.SolidFill.Color = ColorObject.FromArgb(232, 241, 229);
Add title content:
//Add title content to the slide by accessing the title placeholder of the TitleOnly layout-slide
IShape titleShape = slide.Shapes[0] as IShape;
titleShape.TextBody.AddParagraph("Company History").HorizontalAlignment = HorizontalAlignmentType.Center;
Add description content:
//Add description content to the slide by adding a new TextBox
IShape descriptionShape = slide.AddTextBox(53.22, 141.73, 874.19, 77.70);
descriptionShape.TextBody.Text = "IMN Solutions PVT LTD is the software company, established in 1987, by George Milton. The company has been listed as the trusted partner for many high-profile organizations since 1988 and got awards for quality products from reputed organizations.";
Add bullet points:
//Add bullet points to the slide
IShape bulletPointsShape = slide.AddTextBox(53.22, 270, 437.90, 116.32);
//Add a paragraph for a bullet point
IParagraph firstPara = bulletPointsShape.TextBody.AddParagraph("The company acquired the MCY corporation for 20 billion dollars and became the top revenue maker for the year 2015.");
//Format how the bullets should be displayed
firstPara.ListFormat.Type = ListType.Bulleted;
firstPara.LeftIndent = 35;
firstPara.FirstLineIndent = -35;
// Add another paragraph for the next bullet point
IParagraph secondPara = bulletPointsShape.TextBody.AddParagraph("The company is participating in top open source projects in automation industry.");
//Format how the bullets should be displayed
secondPara.ListFormat.Type = ListType.Bulleted;
secondPara.LeftIndent = 35;
secondPara.FirstLineIndent = -35;
Add an image:
//Gets a picture as stream.
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
Stream pictureStream = assembly.GetManifestResourceStream("CreateUWPPowerPoint.Assets.Image.jpg");
//Adds the picture to a slide by specifying its size and position.
slide.Shapes.AddPicture(pictureStream, 499.79, 238.59, 364.54, 192.16);
You can download the image used in the sample from here.
Add a shape:
//Add an auto-shape to the slide
IShape stampShape = slide.Shapes.AddShape(AutoShapeType.Explosion1, 48.93, 430.71, 104.13, 80.54);
//Format the auto-shape color by setting the fill type and text
stampShape.Fill.FillType = FillType.None;
stampShape.TextBody.AddParagraph("IMN").HorizontalAlignment = HorizontalAlignmentType.Center;
Save and close the presentation:
//Initializes FileSavePicker
FileSavePicker savePicker = new FileSavePicker();
savePicker.SuggestedStartLocation = PickerLocationId.Desktop;
savePicker.SuggestedFileName = "Sample";
savePicker.FileTypeChoices.Add("PowerPoint Files", new List<string>() { ".pptx" });
//Creates a storage file from FileSavePicker
StorageFile storageFile = await savePicker.PickSaveFileAsync();
//Saves changes to the specified storage file
await pptxDoc.SaveAsync(storageFile);
//Close the PowerPoint presentation
pptxDoc.Close();
You can download a complete working sample from GitHub.
The output of the above code example will generate the below PowerPoint slide.
Read and edit a PowerPoint file in UWP
You can edit an existing PowerPoint file using this library. The below code snippet demonstrates accessing a shape from a slide and changing the text within it.
//"App" is the class of Portable project.
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
//Open an existing PowerPoint presentation
IPresentation pptxDoc = Presentation.Open(assembly.GetManifestResourceStream("CreateUWPPowerPoint.Assets.Sample_UWP.pptx"));
//Gets the first slide from the PowerPoint presentation
ISlide slide = pptxDoc.Slides[0];
//Gets the first shape of the slide
IShape shape = slide.Shapes[0] as IShape;
//Change the text of the shape
if(shape.TextBody.Text == "Company History")
shape.TextBody.Text = "Company Profile";
//Initializes FileSavePicker
FileSavePicker savePicker = new FileSavePicker();
savePicker.SuggestedStartLocation = PickerLocationId.Desktop;
savePicker.SuggestedFileName = "Output";
savePicker.FileTypeChoices.Add("PowerPoint Files", new List<string>() { ".pptx" });
//Creates a storage file from FileSavePicker
StorageFile storageFile = await savePicker.PickSaveFileAsync();
//Saves changes to the specified storage file
await pptxDoc.SaveAsync(storageFile);
//Close the PowerPoint presentation
pptxDoc.Close();
